detailed description

In order to make the purpose and technical solution of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the utility model. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work all belong to the scope of protection of the present invention:

As shown in the figure: Multi-station polishing machine, including fan motor 1, polishing motor 2, hydraulic cylinder 3, fixture 4, turntable 5, base 6, turntable main motor 7, tooling fixture main motor 8 and screw traction device 9 Wherein, the two polishing motors 2 driving the coarse and fine polishing wheels are on the outside of the flange, and are fixed on the flange with fixing bolts, the rough and fine polishing wheels are on the inner side of the flange, and the rough and fine polishing wheels are directly connected On the rotating shaft of the motor, the rotation of the motor 2 directly drives the rough and fine polishing grinding wheels to rotate at a high speed, so that the grinding wheels perform polishing actions on the surface of the workpiece. The turntable 5 is arranged on the base 6, the turntable main motor 7 and the fixture main motor 8 are arranged under the base 6, and several tool fixtures 4 are arranged on the turntable 5; there are three main motors, and the turntable main motor 7 is used to drive the turntable rotation, the other two are fixture main motors 8, which are used to drive the fixture 4 to rotate. The three main motors are respectively connected with three reducers. The high-speed rotation of the turntable main motor 7 is decelerated by the reducer to reach the ideal speed, and the output shaft of the reducer is transmitted to the axis of the turntable rotation system, so that the rotation of the turntable 5 can be driven; After the main motor of the fixture is decelerated by the reducer, it transmits the decelerated speed to the synchronous pulley, and the synchronous pulley rotates to drive the tensioned belt to move, and finally the belt transmits the speed to the fixture 4, so that the workpiece can be on the fixture Rotate thereupon on fixture 4.
